Leveling up on EShell

My Eshell section has become quite large and more interesting, so I'm
breaking it out into its own file. Also, added the ability to make a
"little Eshell" for a particular file's directory that is quick to end.
Converted Shell functions to Eshell...

I looked at all of the functions I have been carting around for years,
and realized that I could convert them over to Eshell commands. I
could really get rid of normal shell executables like bash and zsh.
No need to keep around this baggage.

Cider is now completely up to snuff...at least, in my book.
Using a customized Powerline Mode-Line

It isn't quite perfect, but it is real close to a clean mode-line view.
Futile attempt to get everything working with Fish

Frustrations with Zshell briefly led me to Fish. It is nice, but
incompatible, and so I don't think I'll bother.
